The article presents the results of comprehensive paleofacial studies in the Bathonian – Boreal Berriasian section on the right bank of the Anabar River (north of Siberia), based on the analysis of lithological, lithogeochemical and paleontological (foraminifera, marine and terrestrial palynomorphs) data. The detailed biostratigraphic subdivision of the section made it possible to trace dynamics of the marine paleobasin in the Anabar Region and paleoenvironmental features on adjacent land areas for narrow time intervals.

Keywords: Bathonian – Boreal Berriasian, north of Siberia, paleofacies, lithology, foraminifera, palynomorphs.
